Effects of Isolated Lumbar Extension Resistance Training on Bone Mineral Density of the Elderly

American College of Sports Medicine
Annual Meeting 1992

ML Pollock, FACSM, L Gazarella, JE Graves, FACSM, DM Carpenter, SH Leggett, D. Lowenthal, MN Fulton, D Foster, J Tucci, RR Mananquil

Study Outcomes & Clinical Relevance:

Six months of specific lumbar extension exercises can increase bone mineral density of the lumbar spine in the elderly.

Can Strong Back Extensors Prevent Vertebral Fractures in Women with Osteoporosis?

Mayo Clinic Proceedings
October 1996 Volume 71, Number 10

Study Outcomes & Clinical Relevance:

Statistical analysis demonstrated a significant negative correlation between the strength of the back extensor muscles and thoracic kyphosis. Significant negative correlations were also found between back extensor strength and the number of vertebral compression fractures and between bone mineral density and the number of vertebral fractures. The negative association between back extensor strength and both kyphosis and number of vertebral fractures suggests that increasing back strength may prove to be an effective therapeutic intervention for the osteoporotic spine. In persons with stronger back muscles, the risk of vertebral fractures will likely decrease.

Effects of High-Intensity Strength Training on Multiple Risk Factors for Osteoporotic Fractures

Journal of The American Medical Association
1994 Volume 272 Issue 24

Miriam E. Nelson, PhD, Maria A. Fiatarone, MD, Christina M. Morganti, MD, Isaiah Trice, PhD, Robert A. Greenberg, William J. Evans, PhD

Study Outcomes & Clinical Relevance:

High-intensity strength training exercises are an effective and feasible means to preserve bone density while improving muscle mass, strength, and balance in postmenopausal women.

Resistance Exercise and Bone Turnover in Elderly Men and Women

Medicine and Science in Sports and Exercise
January 2002 Volume 34, Number 1

Vincent KR; Braith RW Center for Exercise Science, College of Health and Human Performance, University of Florida, Gainesville, Florida

Study Outcomes & Clinical Relevance:

This research project consisted of full body resistance exercise training done exclusively on the MedX selectorized and medical exercise equipment. The data indicates that high-intensity resistance exercise training is successful for improving Bone Mineral Density of the femoral neck in healthy elderly subjects. Also, the data suggests that resistance exercise increases bone turnover, which over time may lead to further changes in BMD. The exercises most strongly correlated with site-specific and total-body Bone Mineral Density were leg press, overhead press, and lumbar extension.

Low Back Strengthening for the Prevention and Treatment of Low Back Pain

Medicine and Science in Sports and Exercise
1999 Volume 31, Number 1

David M. Carpenter and Brian W. Nelson

Study Outcomes & Clinical Relevance:

Isolated lumbar extension exercise with the pelvis stabilized using specialized equipment elicits the most favorable improvements in low back strength muscle cross-sectional area, and vertebral bone mineral density. Improvements occur independent of diagnosis, are long-lasting, and appear to result in less re-reutilization of the health care system than other more passive treatments.

Resistance training prevents vertebral osteoporosis in lung transplant recipients

Clinical Transplantation
15 August 2003, Volume 76, Issue 3

Mitchell, Matthew J., Baz, Maher A., Fulton, Michael N., Lisor, Clem F., Braith, Randy W.

Study Outcomes & Clinical Relevance:

Osteoporosis and vertebral fractures are a consequence of glucocorticoid immunosuppression therapy in lung transplant recipients (LTR). Mechanical loading associated with progressive resistance exercise, using a MedX Lumbar machine, was efficacious in preventing steroid-induced osteoporosis in LTR.
